There were numerous reports the Rwandan government committed arbitrary or unlawful killings: US report

Civilian authorities maintained effective control over state security forces (SSF).

The most significant human rights issues included:

Arbitrary killings and politically motivated disappearances by security forces; torture and other cruel, inhuman, or degrading treatment or punishment by security forces; harsh and life-threatening prison and detention center conditions; arbitrary arrest; security forces’ disregard for the rule of law; prolonged pretrial detention; infringement on citizens’ privacy rights and on freedoms of speech, assembly, and association; restrictions on and harassment of media and some local and international nongovernmental organizations (NGOs); restrictions on freedom to participate in the political process and the ability to change government through free and fair elections; harassment, arrest, and abuse of political opponents, human rights advocates, and individuals perceived to pose a threat to government control of social order; trafficking in persons; and restrictions on labor rights.

The government occasionally took steps to prosecute or punish officials who committed abuses, including within the security services, but impunity involving some civilian officials and some members of the SSF was a problem.
